My Question or Issue

Hello, we are students working on sw project using spotify api. I would like to ask 2 questions regarding using api.

1. As a spotify api, only music is played, and the lyrics are received from an api such as Musicmatch, and the user sings along with the song, records the song, converts it into text, and compares it with the original lyrics to measure the user's pronunciation. Is there anything against the terms and conditions of use?

2. I would like to provide a listening service that plays only music with a spotify api, receives lyrics from an api such as Musicmatch, and writes down the lyrics in the blank while listening to music. Is this also against the terms and conditions of use?
